1.规则目录

/etc/udev/rules.d/

增加一个自己的规则文件

2.例子

KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600000e00d2a0000002a01dd00000000", NAME="lun_ora", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600000e00d2a0000002a01dd00010000", NAME="lun_data", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600000e00d2a0000002a01dd00080000", NAME="lun_index", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600000e00d2a0000002a01dd00050000", NAME="lun_backup", OWNER="grid", GROUP="asmadmin", MODE="0660"
KERNEL=="sd*", SUBSYSTEM=="block", PROGRAM=="/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name", RESULT=="3600000e00d2a0000002a01dd00070000", NAME="lun_admin", OWNER="grid", GROUP="asmadmin", MODE="0660"

3.磁盘信息查看命令

udevadm info -a -p /sys/block/sda/

4.查看磁盘scsi_id以及生效情况命令

ll /dev/disk/by-id

ls /dev |grep lun*

5.udev命令

udevadm control --reload-rules

udevadm trigger

6.查看更多信息

man udevadm

man udev
